Hopefully you'll find that it works everywhere.  :-)

My goal was to make sure LilyPond produces SVG files that comply with
SVG 1.1 and SVG Tiny 1.2, and I'm pretty sure I covered the
inconsistencies between the two recommendations.

Oh, I see, to try converting LilyPond's PostScript output to SVG.  I
understand now.

I've never tried this approach, but if it works okay, this would
probably be the easiest option for now.

It shouldn't be too difficult.  I tried implementing it over the
summer, but gave up due to some strange document-dimension problems I
was encountering.

But those issues might have been resolved in the meantime.

I can't think of any tool that would be useful in this case and still produce
nice-looking SVG output.  "convert" from ImageMagick doesn't work very
well with SVG.

I'll move the output-preview-framework up on my TODO list, since it
would be incredibly useful.
